A modulartotalsynthesis of mycolactone A/B, the exotoxin produced by Mycobacterium ulcerans has been achieved through the orchestration of several Pd-catalyzed key steps. While this route leads to a mixture of the natural product and its C12 epimer (4:1 ratio), this was inconsequential from the biological activity standpoint. Compared to previously reported routes, this synthetic blueprint allows
通过编排几个Pd催化的关键步骤,已经实现了霉菌内酯A / B(溃疡分枝杆菌产生的外毒素)的模块化全合成。尽管此途径导致天然产物及其C12差向异构体(比例为4:1)的混合物,但从生物学活性的角度来看这是无关紧要的。与先前报道的路线相比,该合成设计图允许毒素的后期修饰,例如[22,22,22-2H3] -mycolactone A / B的制备。
Configurationally Stabilized Analogs of <i>M. ulcerans</i> Exotoxins Mycolactones A and B Reveal the Importance of Side Chain Geometry for Mycolactone Virulence
cause of Buruli ulcer. 1a/b represent a rapidly equilibrating mixture of Z/E isomers about the C4′═C5′ double bond of the C5-side chain. Here, we describe the syntheses of mycolactone analogs with configurationallystable C5-side chains (2a, E mimetic; 2b/c, Z mimetics). Based on the cytotoxicity of 2a–c, the Δ4′,5′-trans isomer of mycolactones A/B (1b) appears to be the major virulence factor.
